CONCLUSION.

I cannot help remarking, by way of conclusion, that we have in this

genus of plants a convincing instance of the utility which may

result from the study of natural science in general, and even of

its minuter and hitherto most neglected branches. From a view of

the foregoing memoir it is evident, I presume, that the œconomical

uses of the lichens, in the various parts of the world, are already

very considerable and important: and altho’ it does not appear, that

the sensible qualities of any of them, or the experience of former

ages, will warrant our ascertaining any singular powers to them in a

medicinal way, yet posterity will doubtless find the means of employing

them to many valuable purposes in human life to us unknown.

It will at once be acknowleged, that the vegetable kingdom supplies

us with the far greater share of the necessaries, the conveniences,

and even the elegancies, of life. The cultivation of that knowlege,

which leads to the investigation of its subjects, cannot, therefore,

but be highly useful and necessary: and altho’ the bare science of

natural knowlege is of itself worthy of applause, yet it ought to

be considered, in reality, as the necessary means only of applying

the subjects of nature’s kingdoms to their true ends and purposes,

the service of mankind. To know and distinguish, by determined and

specific characters, even but a small share of that amazing multitude

of objects, with which the great Parent of nature has furnished our

globe, is a task far more than equal to the duration of human life. To

investigate and ascertain their various qualities and uses is equally

arduous and impracticable. While the naturalists, therefore, are

employed in distinguishing the forms of things, let others exert the

united efforts of genius and application to investigate their various

properties and uses. I need not say the field for both is boundless:

it doubtless will be so for ages yet to come. The hopes of discovering

some latent property, which may turn out to the advantage of his

fellow creatures, will animate the man, whose mind is truly formed for

relishing the pleasures of natural science; and however the result may

be, the inspection and contemplation of nature’s productions will ever

afford that satisfaction, which will amply repay him for his trouble.

The minuter, and, as they are commonly estimated, the most abject and

insignificant things are not beneath our notice; and an attentive mind

will readily conceive how much farther, and more extensively useful,

every branch of nature’s kingdom may yet prove in the œconomy of

human life. The man, therefore, whom a genius and love for natural

history has allured into its pursuits, and whose leisure permits his

gratification in such researches, if he is not happy enough to be

crowned with success, at least deserves it, and merits the thanks of

his fellow-creatures for his application and diligence.

XCII. _An Account of the fossile Bones of an Allegator, found on

the Sea-shore, near_ Whitby _in_ Yorkshire. _In a Letter to_ John

Fothergill, _M. D. from Capt._ William Chapman.

Whitby, 20th of 1st mo. 1758.

[Read May. 4, 1758.]

A Few days since we discovered on the sea-shore, about half a mile from

this place, part of the bones of an animal, appearing as in the annexed

figure (_See_ TAB. XXII.). The ground they laid in is what we call

allum-rock; a kind of black slate, that may be taken up in flakes, and

is continually wearing away by the surf of the sea, and the washing of

stones, sand, _&c._ over it every tide.

The bones were covered five or six feet with the water every full

sea, and were about nine or ten yards from the cliff, which is nearly

perpendicular, and about sixty yards high, and is continually wearing

away, by the washing of the sea against it; and, if I may judge by

what has happened in my own memory, it must have extended beyond

these bones less than a century ago. There are several regular strata

or layers of stone, of some yards thickness, that run along the cliff,

nearly parallel to the horizon and to one another. I mention this to

obviate an objection, that this animal may have been upon the surface,

and in a series of years may have sunk down to where it lay; which will

now appear impossible, at least when the stones, _&c._ have had their

present consistence.

_References to the Draught._

_A_, _B_, _C_, the head and bill, not in the same line or range with

the rest of the bones.

_a_, _b_, A bone, with its processes, which I take to be similar to

that, which includes the brain in fishes. The part between the bone and

outlines appeared to be a smooth membrane; but was so thin, that in

taking up it broke.

It is evident this is the upper part of the head inverted.

_B_, _C_, the superior _maxilla_ intire, and in some places covered

with the inferior one for four or five inches together. Where this

happens, the vacuity is filled with matter like the rock in which it

lays; and there are large teeth in each jaw, at such distances, and so

posited, that those in one jaw fill up the vacuities in the other, and

appear like one continued row, the mouth being shut.

Where there is only the superior _maxilla_ remaining, there are

no teeth; but the sockets are visible and deep, and at the same

distances from each other as the teeth in the other part of the jaw.

The tip or extremity of the bill was intire for four or five inches,

having both _maxillæ_, with their teeth, and towards the point large

fangs. Part of the bill and head were covered with the rock; which

was removed before they appeared as in the figure.

_A_, _D_, _F_, _G_, cavities in the rock, about two inches deep, where,

I suppose, the wanting _vertebræ_ have laid, as they are exactly suited

to have received them.

_D_, _F_, Ten _vertebræ_, from three to four half inches in diameter,

and about three inches long, some of them separated in taking up. They

were about two inches in the rock.

_E,_ Here we observed something like bone to stretch from the

_vertebræ_, and intending to take it up whole, begun to cut at what

we thought a proper distance; but found we cut thro’ a bone; and with

the _vertebræ_ brought up three or four inches of the _os femoris_,

with the ball, covered with the _periosteum_: but the animal has been

so crushed hereabouts, that we could make little of the socket or _os

innominata_. Several of the ribs came up with the _vertebræ_: they were

broke, and laid parallel to the _vertebræ_; but not quite close, there

being some of the rock between them. The _periosteum_ is visible on

many of the bones.

_G_, _H_, Twelve _vertebræ_ remaining in the rock, with which they are

almost covered, especially towards the extremity.

The place, where these bones lay, was frequently covered with sea-sand,

to the depth of two feet, and seldom quite bare; which was the occasion

of their being rarely seen: but being informed that they had been

discovered by some people two or three years ago, we had one of them

with us upon the spot, who told us, that when he first saw it, it

was intire, and had two short legs on that part of the _vertebræ_

wanting towards the head. Altho’ we could not suspect the veracity of

this person, we thought he was mistaken; for we had hitherto taken

it for a fish. But when we took it up, and found the _os femoris_

above-mentioned, we had cause to believe his relation true, and to rank

this animal amongst those of the lizard kind: by the length (something

more than ten feet) it seems to have been an allegator; but I shall be

glad to have thy opinion about it.

I am thy friend,

William Chapman _Sen._

Society by_

XCIV. _A further Account of the Effects of Electricity in the Cure of

some Diseases[133]: In a Letter from Mr._ Patrick Brydone _to Dr._

Robert Whytt, _Professor of Medicine in the University of_ Edinburgh,

_and F.R.S._

Coldinghame, January 9th, 1758.

[Read May 11, 1758.]

A Young woman of Aiton, a village about two miles from this place, had

her right leg drawn back by a contraction of the muscles that bend the

knee, so that she had not been able to put that foot to the ground

for near a twelvemonth. She had taken the advice of some Surgeons in

the country, and had used several remedies to no purpose. At last,

hearing of the cure of the paralytic woman, whose case I sent you

some time ago, she insisted on being brought hither; and underwent a

course of electrical shocks for near two months, receiving every day

at least fifty or sixty in the following manner. She sat close by the

machine, and grasping the phial in her hand, she presented the wire to

the barrel or conductor, and drew the sparks from it for about half a

minute. The phial being thus charged, she then touched her knee with

the wire, and thereby received such severe strokes, as would sometimes

instantly raise a blister on the part. The joint was at last so much

relaxed, as that she could walk home with the help of a crutch, tho’

her leg was so weak, that she had very little use of it. After she had

continued in this state for some weeks, she was advised to use the cold

bath: but that soon brought back the contraction; and I have been since

informed that she was worse than ever.

A soldier’s wife, a genteel looking woman, of about 30 years of age,

was seized with a slight palsy, about Newcastle, on her way to this

country: but before she got to this place, she had lost all the feeling

in her left side, and so far the power of it, that she was brought to

us in a cart. After receiving 600 strokes from the electrical machine

in the usual way, and in the space of two days, she recovered the use

of her side, and set out on foot to make out the rest of her journey.

However, for fear of a relapse, I gave her a recommendatory letter

to Mr. Sommer, Surgeon at Haddington, as she was to pass thro’ that

town, and as I knew that he was likewise provided with an electrical

apparatus.

A young woman from _Home_, a village in this shire, but at a good

distance, complained of a coldness and insensibility in her left hand

and wrist, of two years standing. When I felt that hand, it was as cold

as a stone, whilst the other was sweating; and she told me, that it

never had been warmer all that time. I made her draw the sparks from

an egg (which for some other purpose was suspended by a wire from the

conductor) for about half an hour; and at the end of that time I found

the dead hand in a far greater sweat than the other. She then wrapt

it up in a piece of flannel, as she used to do, and retired. Next day

she told me, that since the operation she had been able to put off and

on her cloaths without help, which she had not been able to do for a

twelvemonth before. She was again electrised; and believing she was

then quite well, she went away: but some weeks after, upon the coldness

of her hand beginning to return, she made me another visit, was again

electrised, and was dismissed a second time apparently cured. This is

about two months ago, and I have heard nothing of her since.

As these two last women are at such a distance, I cannot pretend to

send you their own testimony of their cure. But for the two cases in

the separate paper, as the persons are inhabitants of this place, I

have taken care that they themselves should sign them, along with my

father; since you have acquainted me, that accounts of this kind should

have the attestation both of the patients and the minister of the

parish.

I shall only add here, that several persons have been relieved of

rheumatic pains, by electrising the parts affected. And a woman

was cured of a deafness of six months standing, contracted, as she

imagined, by cold. This woman held the phial in her hand, whilst

another person standing on a cake of resin gave her the shock, by

putting the end of the wire into her ear. This manner of electrising

brought always on a profuse sweat over the head, which we encouraged,

by wrapping it up in flannel. The first day she came here, she could

scarce hear what was spoken by those about her; but in five days she

seemed to be perfectly cured.

I am, _&c._

Patrick Brydone.

_Copy of the separate Paper before mentioned._

Robert Haigs, of Coldinghame, a labouring man of about 45, after having

been for ten days ill of a regular tertian ague, at my desire underwent

the electrical shocks in the common way. After having received about

thirty or forty very severe ones, he grew pale, and staggering for

several steps, would have fallen down, had he not been supported. He

then fell into a sweat, which continued near half an hour. I desired

him to come back the next morning, immediately before the fit, which

he said came on about ten o’clock. He accordingly came, and told me he

had not the usual symptoms preceding the fit. He was that day again

strongly electrised; and has been without any aguish symptom ever

since; _viz._ for the space of four months.
